Inspector Detector

Challenge Video

People love treasure hunts. But in this one, kids are looking for something invisible! In this video, kids design and build magnetic-field detectors and use them to find hidden magnets. The video shows kids using the engineering design process, applying a variety of science concepts (e.g., force, magnetic fields, mapping), and learning about how a planet's or moon's magnetic field gives NASA scientists insights into its structure and how it formed.
